The text 'a person not human leads them to the worlds of Brahman' (Bri.
Up. VI. 2, 15) by using the word 'world,' and moreover in the plural,
determines the specification that the not-human person leads those only
who meditate on Hiranyagarbha, who dwells within some particular world.
Moreover, the text 'I enter the hall of Prajâpati, the house' (Ch. Up.
VIII, 14) shows that he who goes on the path beginning with light aims
at approaching Hiranyagarbha. But if this is so, there is a want of
appropriate denotation in the clause, 'There is a person not human, he
leads them to Brahman'; if Hiranyagarbha is meant, the text should say
'He leads them to Brahmâ (Brahmânam).'
